Most net-zero scenarios include carbon removal as a major component. Simon Göss at cr.hub reviews five major scenarios from the IPCC, IEA, ETC, McKinsey, and the Network for Greening the Financial System (NGFS). He starts by making the very important distinction between carbon capture and negative emissions: capturing carbon from, say, a gas plant does not deliver negative emissions, it just prevents new emissions. This article is about the … [Read more...]
How to grow grid-scale U.S. Battery capacity to 125GW (or even 680GW) by 2050
Grid-Scale U.S. storage capacity could reach 125GW by 2050, or even as much as 680GW, according to research from NREL. Almost all today, under 25GW, comes from pumped hydro which has probably reached its limit so the future is batteries. Growth depends on commercial viability, so the research led by NREL has modelled what services storage can supply, the main three being firm capacity, energy time-shifting and operating reserves. The sets of … [Read more...]
Improving cost and performance modelling for energy technologies, old and new
Measuring the performance of an energy technology is key to informing policies and pathways as the transition scales up. But are we measuring all the right things and getting accurate answers? If we’re not, those policies and pathways could end up wrong. Paul Sapin at Imperial College, UK, explains how they are creating a library of data-rich models to greatly improve predictive power for all energy technologies, both existing and emerging. He … [Read more...]
